GQ-3680Q

上市日期: 2020-04-09

Main Features

· Modular card design, easy to upgrade and maintain

· With GbE Gigabit Ethernet input and loop-out, single interface up to 960Mbps data throughput

· Support UDP, RTP, IGMP and other data transmission protocols

· Supports management and control using HTTP, SNMP and other protocols

· With 1 + 1 optical interface (or electrical interface) redundant backup to ensure high reliability of data reception

· With high integration, stand-alone 1RU achieves 16, 32, and 48 frequency points of RF radio frequency signal output

· Comply with ITU-T J.83 Annex A, B international standards, compatible with DVB-C standards

· Each frequency point can reuse up to 64 sets of programs, each program has 16 PID processing capabilities


Q-3680Q is a new generation of multi-function modular IPQAM modulator from Gauss Bell. It can receive MPEG / II transport stream encapsulated by UDP / RTP with multiple IP input, and multiplex, scramble and insert local information. , And then perform QAM modulation, and finally output the RF signal.

GQ-3680Q can be applied to the front-end of cable digital television stations, sub-front-end computer rooms, or editing and broadcasting centers. A single device can meet the diverse information processing needs of customers; it can also be used as an edge IPQAM modulator under the VOD system architecture.
